Final answer:
The Tuskegee Study was a research study conducted from 1932 to 1972. Participants were told they were being treated for a disease called "bad blood," but were actually being observed for the effects of untreated syphilis. They were never provided with the available cure for syphilis.
Step-by-step explanation:
The Tuskegee Study, also known as the Tuskegee Syphilis Study, was a research study conducted by the U.S. Public Health Service from 1932 to 1972. African American men from Tuskegee, Alabama were recruited to participate in the study, with the promise of free medical care, meals, and burial insurance. However, the participants were not informed that they were diagnosed with syphilis. They were told that they were being treated for a disease called "bad blood." The study aimed to observe how untreated syphilis affected the African American men over time, and even when a cure for syphilis became available, the participants were not provided with the treatment.
